Hello, John. I am looking for a long-term technical mentor for my son David, who is completing a master’s degree in Biology with a bioinformatics focus.
His graduate project is called the Organelle Quality Hub. It is a scientific web application built with Python, Django, and PostgreSQL. The platform will store existing information about mitochondrial and chloroplast genomes. Users will be able to search, filter, compare, and visualize records. It will also include a metadata-completeness indicator showing which expected fields are present or missing. David already has part of the website and database working. He needs guidance reviewing the existing architecture, organizing the remaining work, resolving technical problems, importing and validating data, testing the application, and completing weekly deliverables. We are not looking for someone to build the application for him. David wants to write, test, and understand all the code himself. The mentor should guide him through screen-sharing sessions while David controls and modifies the code. We are looking for support throughout the semester, with the possibility of continuing for the full academic year. Our initial plan is: - Two virtual sessions per week - 60 minutes per session - Eight sessions per month - Long-term technical guidance and code review I would like to confirm: 1. Do you have strong experience with Django and PostgreSQL? 2. Have you mentored students or junior developers through a complete software project? 3. Can you review an existing application and create prioritized weekly deliverables? 4. Are you comfortable teaching through screen sharing while David controls the code? 5. Have you worked with scientific data, genomics data, NCBI, GenBank, or other structured research databases? 6. Are you available for two sessions per week throughout the semester? 7. What monthly package rate would you offer for eight 60-minute sessions? 8. Would you offer a reduced rate for a semester-long arrangement? 9. Are you available for one paid trial session this week? This is a mentoring role, not a development outsourcing role. Thank you.

AI Developer: secure client-hosted knowledge systems, retrieval, agents, applied AI
Applied
|
not specified | 9 hours ago |

|
I am building a secure knowledge system that gets deployed inside a client's own environment, and applications that run on top of it. I need someone who has done this before: not a chatbot demo, but a real system holding confidential material that people rely on daily and that has passed an enterprise security review.
Security The data going into these systems is confidential customer research, unpublished strategy, client work under NDA, and in some cases commercially sensitive material that would cause serious damage if it leaked. The system therefore lives with the client, inside their own infrastructure and their own security perimeter, running against their model provider. Nothing sits in a shared environment I control, and nothing routes through a third party the client has not already approved. That decision shapes the architecture from the first line of code rather than being a setting we switch on later. Encryption at rest and in transit, access control that mirrors the permissions structure the client already has, audit logging detailed enough to answer "who saw what, and when" a year after the fact, and a deployment model that can survive an infosec questionnaire and a penetration test. What I want built A secure, client-hosted knowledge system. I'd like to build two versions: Version one is for agencies. It will ingest everything they have produced: past pitches, case studies, sector points of view, research decks, articles nobody has opened since 2019, and make it genuinely searchable and usable. Two ways in: a chatbot their team can ask questions of, and a live connection that other AI tools plug into and work from. The second matters more than the first. When someone is writing a proposal, they should be able to pull the three most relevant case studies without already knowing those case studies exist. When someone is drafting an article, they should be building on the firm's own published position rather than starting from nothing. The hard part is not the chat interface. It is that half the corpus is PowerPoint, the argument lives in slide layouts and chart images, and the metadata is whatever someone typed into a filename in 2017. Version two is for insight teams inside large organisations. Same spine, higher stakes. Years of research reports, survey data, focus group transcripts, tracker studies and brand health work, ingested and organised so an insight manager can answer a question in ninety seconds instead of emailing three colleagues and waiting a day. The applications that sit on top The data centre is the foundation, not the product. Once it exists, everything interesting happens in the layer above it, and this is where I expect most of the build effort to go over time. A voice interface, because asking a question out loud and getting a straight answer back is a different behaviour from searching, and it puts the material into meetings and workshops where nobody is going to stop and open a search box. Persona generation grounded in the client's actual research rather than invented, so that a persona is traceable back to the studies and quotes it came from and can be interrogated rather than just read. Predictive modelling and simulation against the insight base: forecasting how a segment behaves, testing a proposition against what the research already says about the people it targets, running scenarios before anyone commissions new fieldwork. Proactive research that runs on its own initiative against a defined customer profile, finds what has changed in that customer's world, and files it back into the vault with full provenance. I am being deliberate about the order. Retrieval has to be excellent before any of this is worth building, because every application above inherits its accuracy from the layer underneath. What the job actually involves Early on, the unglamorous half: an ingestion pipeline that handles PowerPoint, PDF, Word, spreadsheets and transcripts without quietly losing the content that matters, and a chunking and metadata approach that makes the difference between search that works and search that returns plausible nonsense. Then the retrieval layer, and a way of measuring whether it is any good. I want to know when a pipeline change has made results worse, and I want to know it from an eval set rather than from a client telling me. Then packaging the whole thing so it deploys repeatably into very different client environments, AWS in one, Azure in another, each with their own identity provider, their own approved models and their own rules. This is the engineering problem that decides whether the product scales past the first two clients, and it is easy to underestimate. Then the interfaces and the applications above: chat, a connection layer so other AI tools can query the vault as a live source, voice, personas, simulation. Experience that you'll need Shipped a retrieval system into production that people used regularly, and can talk in detail about how you improved its accuracy over time Built and deployed software into a client's own cloud environment rather than only running your own Handled real security requirements: SSO and SAML, role-based access down to document level, encryption, audit logging, and the paperwork that comes with selling into large organisations Built document ingestion for genuinely awkward formats, especially slide decks Worked seriously with vector search, whether that is pgvector, Qdrant, Weaviate or something else, and can explain why you chose it Strong backend engineering, most likely Python or TypeScript, with enough infrastructure and deployment knowledge to run this without me hiring a second person Useful, not essential Voice and realtime speech pipelines. Agent orchestration and tool use. Writing MCP servers. A statistics or data science background, which matters for the simulation and persona work more than for the retrieval work. Experience taking a product through a corporate infosec review. Practicalities Contract to begin with, [x days a week], reviewed after the first build. Remote is fine but needs to be at least 3 hrs with GMT, because I want to be able to talk things through the same day rather than the next one. Rate depending on experience. There is a real chance this becomes something longer and larger if the first builds land, and I would rather find one person to grow with than run a series of short engagements. How to apply Apply with a short note covering two things. One: the hardest retrieval or search quality problem you have solved, what you tried that did not work, and how you knew when it was fixed. Two: the thing in this spec you think I have got wrong. Thanks

We operate multi-store e-commerce brands on Shopify in two main verticals:
Home & Furniture: A large catalog (250,000+ SKUs dropshipping + local manufacturing) and a separate premium furniture storefront. K-Beauty & Cosmetics: A dedicated store curating trending Korean skincare products and active formulations. We already have PPC and technical teams running campaigns. What we are missing is commercial merchandising intelligence. We need a seasoned e-commerce strategist to build a practical, data-driven system to spot product trends, track competitor prices, and pick high-margin "Hero Products" before we spend a single euro on advertising. Key Deliverables & Responsibilities 1. Trend Hunting & Product Discovery System: Build a weekly workflow to spot upcoming product trends in Furniture & Home Decor (EU/Global trends) and Korean Skincare / K-Beauty (viral ingredients, trending brands, social commerce spikes). Define specific data sources (Google Merchant Center Insights, Pinterest Trends, Amazon Movers & Shakers, TikTok Creative Center, Olive Young benchmarks). 2. Competitor Price Intelligence & Monitoring (MVP): Set up an automated or semi-automated price-tracking system (using Google Merchant Center Price Competitiveness, scrapers, or tools like Price2Spy/Prisync) to benchmark our prices against competitors daily. 3. SKU Selection & Unit Economics Matrix: Create a mathematical filtering framework (in Google Sheets/Excel) to review supplier catalogs (1,000–50,000 SKUs) and select the top 30–50 Hero SKUs based on demand, gross margin (above 35%), retail price (above €80 for furniture), and shipping feasibility. Identify high-elasticity products to help us negotiate volume discounts with suppliers. 4. Pricing & Shipping Strategy: Optimize our pricing and shipping models (e.g., product price + shipping vs. higher price with free shipping) for Google Shopping rank vs. on-site conversion rate. 5. 12-Month Commercial Seasonal Calendar: Map out a 12-month promotional calendar covering seasonal peaks, supplier lead times, and promotional bundle concepts for both niches. Who We Are Looking For Proven experience as an E-Commerce Merchandiser, Category Manager, or Commercial E-Commerce Strategist. Practical experience in Home/Furniture OR K-Beauty/Cosmetics (experience in both is a major plus). Deep understanding of Shopify, Google Merchant Center (Market Insights, Price Competitiveness, Best Sellers), and feed segmentation. Hands-on ability to build clear, usable spreadsheets and dashboards (no complex theoretical slides—we need functional tools). Screening Questions (Please answer when applying) Have you built a product trend discovery or competitor price tracking system for an e-commerce brand before? Please share a brief 2–3 sentence example. What tools or workflows would you recommend to track K-Beauty and Furniture trends without spending thousands on enterprise software? What is the first thing you would build in the first 48 hours as an MVP for this project?

I’m looking for an experienced Senior/Staff Software Engineer to help me work through advanced software-engineering benchmark and AI-evaluation projects, primarily involving Mercor Hard Colosseum–style tasks and Snorkel software-engineering benchmark projects.
These projects involve realistic software-engineering problems such as understanding existing repositories, debugging complex issues, implementing fixes, reviewing code, working with tests, understanding grading requirements, and identifying edge cases. I am looking for someone who can work with me as a technical coach, pair programmer, debugger, and code reviewer. You should be comfortable jumping into unfamiliar repositories and quickly understanding: Existing architecture Task requirements Failing tests Hidden edge cases Repository structure Build/test environments Docker or containerized environments CI/CD behavior Git/GitHub workflows Code correctness beyond simply passing tests What I Need Help With You may help me with tasks such as: Understanding difficult benchmark/task requirements Reviewing task specifications before implementation Exploring unfamiliar GitHub repositories Identifying the relevant parts of a large codebase Debugging failing builds and tests Explaining why tests are failing Finding edge cases that may not be immediately obvious Reviewing my implementation before submission Suggesting cleaner or more robust solutions Identifying regressions introduced by a change Running and interpreting test suites Understanding Docker-based development environments Troubleshooting environment/setup issues Reviewing patches and Git diffs Evaluating whether a solution actually satisfies the requirements Helping distinguish between a solution that merely passes visible tests and one that is genuinely correct Improving development speed when working through unfamiliar projects The goal is not simply to generate code, but to reason carefully about each engineering problem and make sure the resulting implementation is technically sound. Typical Workflow For each task, we would generally: Review the task requirements together. Inspect the repository and existing architecture. Identify the files/components involved. Discuss the likely implementation approach. Work through difficult implementation or debugging issues. Run the available tests. Investigate failures and edge cases. Review the final diff. Check for regressions, maintainability issues, and hidden failure scenarios. Make sure I fully understand the solution before completing the task. Required Experience I’m looking for someone with strong real-world software-engineering experience. You should have significant experience with several of the following: Python TypeScript / JavaScript Go Rust C# / .NET React / Node.js Backend development REST APIs SQL / databases Linux Git GitHub Docker CI/CD Automated testing Unit and integration testing Debugging unfamiliar codebases You do not need to be an expert in every language. More important is your ability to understand unfamiliar systems quickly and reason through difficult engineering problems. Strongly Preferred I’m especially interested in engineers who have experience with: Senior or Staff-level software engineering Open-source projects GitHub pull-request reviews SWE-bench or similar coding-agent benchmarks AI coding-agent evaluation LLM evaluation Benchmark creation or validation Repository-level coding tasks Debugging complex test failures Codebase modernization Reviewing AI-generated code Finding subtle bugs that automated tests miss Experience with tools such as Claude Code, Cursor, Codex, GitHub Copilot, or other AI coding agents is also useful. What Makes a Good Fit You are probably a good fit if you can open an unfamiliar repository and quickly answer questions like: Where is the bug most likely located? What behavior is the task actually asking us to change? Which tests should cover this behavior? What could break if we modify this component? Is this fix addressing the root cause or only making the test pass? What edge cases are missing? Is the implementation consistent with the existing architecture? Could a hidden test expose a weakness in this solution? I value reasoning and engineering judgment much more than simply producing code quickly. Working Arrangement This will initially be a small engagement, but it may become ongoing work if we work well together. I would prefer someone who can occasionally collaborate through: Upwork chat Screen sharing Pair-programming sessions Code review Git diffs / patches Repository walkthroughs Please let me know your availability and preferred working style. Important All work must follow the applicable project/platform rules. I am specifically looking for technical guidance, debugging assistance, pair programming, and code review. You should not access my account, impersonate me, or submit work under my identity. When Applying Please include: Your years of professional software-engineering experience. Your strongest programming languages. Your experience debugging unfamiliar repositories. Your experience with GitHub pull requests and code reviews. Any experience with SWE-bench, coding benchmarks, AI evaluation, or AI coding agents. Your experience with Docker/Linux development environments. Your hourly rate. Your availability. A short example of a difficult bug or engineering problem you diagnosed. Screening Question Suppose you receive a task in an unfamiliar repository. Your implementation passes all existing tests, but you suspect that hidden tests may still fail. How would you determine whether your implementation is actually correct rather than simply overfitting to the visible tests? Please give a short but technical answer. Engagement Type Hourly / ongoing as needed Potential for longer-term collaboration if the first few tasks go well.

|
||
|
We are an early-stage AI healthcare company looking for an exceptional "Senior Machine Learning / AI Engineer" to build a recommendation and Next-Best-Action engine using several years of longitudinal patient treatment and transaction data.
The core problem is to identify and validate patterns in historical patient behavior, then use those patterns to predict: * What a patient is most likely to do next * When they are likely to return * What additional services are most relevant to recommend * How confident we should be in each prediction The project will have two phases: Phase 1: Pattern Discovery & Validation Analyze historical patient journeys to identify statistically meaningful same-visit affinities, treatment sequences, next-visit behavior, and return timing. Phase 2: Predictive Next-Best-Action Engine Build and backtest a patient-level recommendation engine using the validated patterns from Phase 1. We are specifically looking for someone with strong experience in **recommendation systems, behavioral prediction, sequential modeling, applied machine learning, and transactional datasets**. This is not primarily an LLM or generative AI project. We care about statistical rigor, explainability, strong baselines, backtesting, and production-quality ML. Healthcare experience is helpful but not required. Prior experience building recommendation, personalization, or Next-Best-Action systems is highly preferred. Required Application Questions **Please answer all five questions below. Applications that do not answer them will not be considered.** 1. What is the most relevant recommendation, personalization, or Next-Best-Action system you have personally built? Briefly describe what you predicted, your approach, and how you measured performance. 2. You have several years of customer transaction history and need to predict what a customer will purchase next and when they will return. How would you approach this problem? Please keep your answer to 5-10 sentences. 3. How would you determine whether Treatment A actually increases the likelihood of Treatment B versus Treatment B simply being popular overall? Briefly explain the methodology you would use. 4. How would you evaluate a Next-Best-Action model using historical data without introducing data leakage? What metrics would you use to decide whether it is good enough to put into production? 5. Please share one relevant GitHub repository, technical case study, portfolio example, or project you personally built. Clearly state which parts you designed and implemented yourself.

The goal is to replace portions of a traditional SPICE run with a machine-learning proxy that can predict multiple analog metrics at once (delay, power, noise, etc.) from layout-level or netlist-level features.
Key details • Scope: pure simulation workflow; no verification or post-layout optimisation tasks are needed. • Model choice: XGBoost Multi-Output Regressor is fixed. • Critical tweak: I need a custom number of estimators rather than the default setting; help me decide and implement the optimal value through systematic tuning. What I expect from you 1. Clean, reproducible Python (preferably a Jupyter Notebook) that: – Pre-processes my CSV/netlist-derived dataset, – Trains and cross-validates the XGBoost model, – Outputs predictions for all target metrics in a form that can slot back into my current simulation flow. 2. Brief documentation describing feature engineering choices, chosen estimator count, and any other hyper-parameters. 3. A short note on how to extend the model to new process corners or larger datasets. Tools on my side I’m already set up with Python 3.10, scikit-learn, and xgboost on an Ubuntu workstation, so please align with that stack. Deliver the notebook, a requirements.txt (if extra libraries are needed), and a sample run showing the model converging and producing multi-output predictions. If everything runs smoothly on my end and the metrics meet or beat my current SPICE run time/accuracy trade-off, the job is finished. Skills: Python, Data Processing, Electronics, Machine Learning (ML), LabVIEW, Arduino, Data Science, Data Analysis

I’m putting together an end-to-end computer-vision pipeline that can automatically recognise and classify nature and landscape photographs. The core goal is a reliable image-classification model that can take a raw photo—forest, desert, coastline, mountain range, or any other natural scene we decide on—and return the correct label with strong accuracy.
Here’s what I need from you: • A well-structured dataset or clear guidance on sourcing and curating one (public sets are fine as long as licensing is respected). • A training workflow in Python using a mainstream framework such as TensorFlow or PyTorch, complete with data-augmentation, fine-tuning, and validation steps. • Trained model weights plus inference code that runs on CPU or GPU with a single command. • A concise README explaining environment setup, training parameters, and how to add new classes later. • Evaluation metrics (precision, recall, confusion matrix) so I can judge performance quickly. Acceptance will be based on reproducible training, cleanly commented code, and meeting an agreed-upon accuracy threshold on a held-out test set. If you’ve tackled similar nature-scene projects or have transfer-learning tricks up your sleeve, let’s get started—I’m ready to move fast once you are.

Fixed price AU$1,111 across four milestones, 3–4 weeks. Australian Registered Training Organisation (RTO 31871) needs a working pipeline that turns a messy SharePoint/OneDrive folder tree into a clean, indexed, AI-searchable knowledge base: deduplicate, convert Word/Excel/PowerPoint/PDF into Markdown twins with a standard YAML metadata header, generate a manifest index that resolves any question in one hop, apply a five-value classification scheme, and run an automated quality gate that blocks on a planted breach. Plus two scheduled agents and a runbook. Final milestone is a watched, unassisted pipeline run by our own manager. You build against a sanitised sample only — no live or student data.

I hold an MSc in Software Engineering and am applying for a fully funded PhD in Computer Science. I currently do not have a finalized research topic.
I want to hire an academic consultant (PhD holder or university researcher) to help me identify a viable topic, find an open research gap, and structure a high-impact research proposal. To ensure my PhD is resilient against AI automation, my current preferences lean toward choosing a topic within one of the three high-demand Computer Science tracks listed below; however, I am fully open to new, innovative ideas if you have a stronger track in mind: 1. The Autonomous Agent Track: Multi-agent collaboration frameworks to automate complex enterprise software workflows. 2. The Neuro-Symbolic AI Track: Combining deep learning pattern recognition with logic-based computer science to build trustworthy, hallucination-free AI systems. 3. The Scalable Infrastructure Track: Optimizing algorithms to train and run massive models using drastically less compute power and energy. IMPORTANT: Clarification on Scope (Phase 1 Focus) Please note: We are NOT writing any proposal text during the initial milestones of this contract. The immediate goal of this project is strictly strategic. We are focusing 100% on identifying, validating, and locking down a viable, technically achievable research topic with a verified gap in current literature. Do not apply if you expect to immediately sit down and write a document. I am paying for your academic brainpower, market awareness, and technical vetting skills to ensure I do not get stuck with a bad topic later. Milestone-Based Deliverables (To Avoid Getting Stuck): This contract will be managed strictly via 4 distinct milestones. Payment will be released only upon the successful completion of each deliverable: 1. Milestone 1: Topic Selection and Refinement ( Deliverable: A 1-hour brainstorming session resulting in 3 concrete, specific research questions mapping my Software Engineering background to one of my preferred tracks or your newly suggested alternative. 2. Milestone 2: Literature Gap Validation Deliverable: A curated list of at least 5-7 recent peer-reviewed papers (IEEE, ACM, NeurIPS) showing exactly where the current research ends and where my proposed topic begins. 3. Milestone 3: Proposal Outline and Methodology Deliverable: A structured written outline detailing the proposed technical approach, algorithmic methods, and evaluation criteria for the chosen topic. 4. Milestone 4: Final Draft Review Deliverable: Line-by-line academic review and polishing of my final 2-to-3 page proposal to ensure it meets rigorous CS department entry standards. Candidate Requirements: 1. Must hold a PhD in Computer Science specializing in Artificial Intelligence, Machine Learning, or Distributed Systems. 2. Must have a proven track record of writing or reviewing successful doctoral research proposals. 3. Must act as a mentor/collaborator who guides the methodology; ghostwriters will be immediately reported. Screening Questions for Applicants: 1. Based on my preferences (Agents, Neuro-Symbolic, Scalable Infrastructure) or your own vision, what specific Computer Science direction do you think holds the highest dynamic potential right now? 2. Briefly describe how you would help a student narrow down a broad idea into a specific, fundable CS research question during a 1-hour call without starting any structural draft writing.
